Iguazu Fall

Iguazu Falls is located where the Iguazu River tumbles over the edge of the Paraná Plateau, 23 kilometres (14 mi) upriver from the Iguazu's confluence with the Paraná River. Numerous islands along the 2.7-kilometre (1.7 mi) long edge divide the falls into about 275 separate waterfalls and cataracts, varying between 60 metres (200 ft) and 82 metres (269 ft) high. About half of the river's flow falls into a long and narrow chasm called the Devil's Throat (Garganta del Diablo in Spanish or Garganta do Diabo in Portuguese).  The Devil's Throat is U-shaped, 82-meter-high, 150-meter-wide, and 700-meter-long. The border between Brazil and Argentina runs through the Devil's Throat.

About 900 meters of the 2.7-kilometer length does not have water flowing over it. The edge of the basalt cap recedes by 3 mm (0.1 in) per year. The water of the lower Iguazu collects in a canyon that drains in the Paraná River, a short distance downstream from the Itaipu Dam. The junction of the water flows marks the border between Brazil, Argentina, and Paraguay. There are points in the cities of Foz do Iguaçu, Brazil, Puerto Iguazú, Argentina, and Ciudad del Este, Paraguay, which have access to the Iguazu River where the borders of all three countries can be seen, a popular tourist attraction for visitors to the three cities.

There are two international airports close to Iguazú Falls: the Argentine Cataratas del Iguazú International Airport (IGR) and the Brazilian Foz do Iguaçu International Airport (IGU). Argentina's airport is 25 kilometers from the city of Iguazu but closer to the Falls hotels than his Brazilian counterpart, there is bus and taxi service from and to the Airport-Falls. Brazil's airport is between Foz do Iguaçu, Brazil and the falls. LAN Airlines and Aerolíneas Argentinas have direct flights from Buenos Aires to Iguazu International Airport Krause and several Brazilian airlines as TAM Airlines, GOL, Azul, WebJet offer service from the main Brazilian cities to Foz do Iguaçu.

Bu Tinah Island

Bu Tinah is a tiny archipelago amid extensive coral formations and seagrass beds some 25 km south of Zirku and 35 north of Marawah in the United Arab Emirates.[1] Found in the waters of Abu Dhabi, it is protected as a private nature reserve. Bu Tinah Island, rich in biodiversity, lies within the Marawah Marine Biosphere Reserve with a territory of more than 4,000 sq km. The Biosphere reserve is the region's first and largest UNESCO-designated marine biosphere reserve. It has been a recognised UNESCO site since 2001. Closed to visitors, fishing and the collection of turtle eggs are prohibited on Bu Tinah Island, the ban being enforced by patrols. Bu Tinah is actually a cluster of islands and shoals, joined or almost so at low water, with nowhere greater than two or three metres above sea level. The main island has a sheltered lagoon opening to the south with the low energy environment permitting stands of mature mangrove to flourish.Even birds like Socotra Cormorant are found here.

There are also healthy coral reef habitats with as many as 16 species of coral recorded in the area. And the reefs survive in conditions that would kill coral species in other parts of the world. The Gulf's waters are among the most saline in the world, as well as among the warmest. Corals live in water that is between 23°C and 28°C but in the UAE water temperatures go as high as 35°C in summer.
